Occasional ContributorAltera USB Blaster III LEDs usage
Hi AnttiLukats,
Thank you for your patience, and I sincerely apologize for not addressing your question directly in my earlier reply.
Regarding your inquiry about the meaning of the RGB LED colors on the on-board USB Blaster III, please find the detailed information below:
- Off: No power / not connected / suspend mode
- Blue: Connected, not in use
- Green: Connected, an application is using JTAG, no traffic
- Green flickering: Connected, data is moving through the JTAG interface
- Purple flashing: Identify function has been triggered on this cable
If you have further questions or need additional clarification, please don’t hesitate to reach out. I'm here to help and will ensure your concerns are addressed promptly.
Thank you again for bringing this up, and I appreciate your understanding.
Best regards,
Fakhrul
Occasional ContributorIf you look at the Quartus installation files you find a file with _blaster3_ in the name. If you look inside that file you see string: "USB-BlasterIII" ! Also found in that file are links to FTDI DLL's. So it seems Quartus will soon support FTDI based USB Blaster III hardware. Pretty exciting!
Super ContributorHi,
Installation files of which Quartus version? You have been initially asking about RGB-LED, suggesting that have seen a picture, manual or real hardware of claimed USB Blaster III.
Recent Quartus versions have this driver folders
